NULL — there is money on the blockchain
Credibility concern recorded. The source reference remains available for verification and correction.
A riddle game hides real-money prizes on a public blockchain and pays the first correct answer through a contract.
Field notes
NULL presents each challenge as a public-ledger investigation rather than a conventional puzzle page. Clues may point to an address, transaction, or note, and the stated submission flow checks the answer locally before sending only a hash. The site identifies the winning rule as the earliest correct entry and says prizes are funded in a contract before publication. Its visible status is currently “IDLE,” while archive and activity links point to prior or additional rounds.
